Blood Wound

You begin to make the blood of those around you boil, causing excruciating pain in an aura within a 15-foot radius. Until the spell ends, the aura moves with you, centered on you. When a creature enters the aura for the first time on a turn or starts its turn there, the creature must succeed in a Con saving throw or take 2d6 necrotic damage and be incapacitated until the end of its next turn. A creature that succeeds on its saving throw takes half as much damage and is not incapacitated.

At Higher Levels: When you cast this spell using a spell slot of 5th or higher, the damage increases by 1d6 for each slot above 4th.
